I have a few problems at the moment, seeningly related to the ancient Univolt, or maybe my battery needs replacing? Not sure how to tell. Electrically clueless.
I look forward to learning from you all!!
The easiest is to test each battery cell, with a hydrometer.
A difference of 25 points or more, betwwen the best and worst cell, render that battery "bad" when used with any RV automatic charging system.
A difference of 50 points, is maximum for a car battery, which has a different charging system.
However, if the battery is more than 4 or perhaps 5 years old, you can almost bet that it has gone south.
If the battery tests OK, then you can test the "loaded" Univolt output.
It should not ever exceed 14.2 volts DC. If it does, it will overcharge the battery.
